4 Claims. (Cl. 118-268) lThis invention relateskgenerally to ink applicators and particularly to a cartridge type ink applicator.

In the past, it has beenA proposed to provide ink applicators `of a character having an ink container, or well from which `a wick projecting externally of the container vapplies the ink by contactto an inking roller for ultimate application to printing elements. One of the objections to such devices is ink leakage by capillary action during storage of the devices, which leakage becomes more active when the pressure in the container increases with accompanying increase in ambient temperature. This not only causes a loss of ink, but also renders ,the ink stained containers objectionable to handle. To overcome this condition, it has -been proposed toprovidea cap over the exposed end of the wick and seal it to the container. However, such caps and their application to containers are expensive and the successful sealing of them to the container -is very diliicult, particularly where a broad wick is required. Y

Accordingly, it is an object of the invention to provide an improved cartridge type ink applicator in which the above mentioned objections are obviated.`

Another object of the invention is to provide an improved cartridge type ink applicator in which the above mentioned leakage problem is solved without need of sealing the wick outlet of the ink container.

Another object of the invention is to provide an improved cartridge type ink applicator .in whichl the ink is separated `from the wick by aipressurized iniiatable capsule,

punoturable when ydesired to effect contact between ther ink andl wick.

Other objects of the invention will become apparent from the following description, taken in connection with the accompanying 'drawings in which:

FIG. 1 is an end elevation of my ink cartridge shown in association with ink transfer rollers;

FIG. 2 is a plan view partly broken away and in section of the ink cartridge;

' FIG. 3 is a horizontal sectional view partly in elevation and taken along the line 3--3` of FIG. 1;

FIG. 4 is a vertical cross sectional view taken along FIG. 5 is a plane view of a cover `of the ink cartridge;

FIG. 6 is a perspective'view of the ink cartridge;

FIG. 7 is an end view of the ink cartridge Iwith the cover removed;

FIG. 8 is a cross sectional View similarto FIG. 4, showing a modification; Y

FIG. 9 is a sectional view taken longitudinally of the modified ink cartridge along the line 9-9 of FIG. 8,

ployed to apply ink to a metal transfer roller 16l in contact with a distribution roller 18A lfor applying ink to one or more printing wheels 20, as illustrated in FIG. 1.

In order to provide an ink cartridge from which ink cannot leak during storage of the cartridge and yet one which can be readily placed in use, I provide within the l 3l, i @4,988 Patented` Sept. 24, v 1963 CCA container 10 a puncturable capsule 22 containing the ink so as to separate the ink from the wick 12. That is, the wick 12 is within the container 10; but Without the ink capsule 22. The capsule 22 may be made of any suitable material that may be easily fractured, such as a frangible thin glass lwall structure or plastic material capsule. However, I prefer to use an expansible-conftractable inflatable capsule ofthe structural character of toy rubber balloons, but preferably made of a higher quality of latex with a thin strong wall 4and a iiller neck 24 (see FIG. 8).

Any suitable container may be used, the .present container 10 being box-like in construction having a bottom wall 24, side walls 25 and 26, end walls 28 and 3i]l and a top wall 32. Preferably the container 1.0' is made of a plastic material or thermo-setting resin of suiiicient degree of transparency to allow visual inspection of the quantity of ink remaining therein. The top Wall 3-2 of the cartridge 10 is made separately [from the cartridge proper, as a cover, and is cemented to the rupper edges of side walls 25, 26, and end walls 28, after the wick 12 and ink capsule 22 are placed within the container. Any suitable cement, such as any of the well-known resin cements, may be employed to secure and seal the top wall 32 to the upper edges of the container side and end 4wall. The top wall 3-2 is provided with a hole partially therethrough leaving a thin frangible cr puncturable vane 31.

The wick 12 is preferably T-shaped having a stem or j leg portion 34 extending along the container bottom wall 22 and then upwardly along the side Wall 26 to the top wall 32 Where the cross portion 36 of the T-shaped wick is held in the outlet 14, as shown in FIG. 4. In the edge of top lWall 32 and adjacent the side wall 26 of the con- I tainer kltlt there is provided a recess 38 to receive the upper end portion 36 of the wick. VProjecting upwardly from the top wall 32 and extending along the recessed edge thereof is a wick retainer member or flange 40 and onthe otherside of the Wick there is provided' an upstanding wick back-upmember 42 which is preferably formed as an extension of the cartridge side wall 26. The back-up member 42 lits snugly into the recess 38y and with the retainer member 4t)I form a wick restricting passage, the wick being tightly clamped between the retainer member 40 and the back-up member 42. By making the wick T- shaped the amount of ink supplied to the wick cross portion 36 is controlled to avoid the application of an excess of ink, and I further reduce the amount of ink applied to roller 16 by having only end tap portions 44 of the wick for contact with roller 16.

The back-up member 42 terminates just below the upper end of the wick 12 and gives support to the other- Wise flexible Wick to keep the Wick tab portions 44 in contact with the periphery of roller 1.6. The back-up member `42 terminates at its opposite ends inwardly of the cartridge end walls 26, 28, respectively, and fits snugly between the ends, as at 46 :of the wick restricting passa-ge. Integral with the recessed edge 38 of the top wall 32 there is ya pair of horizontally spaced locators or pins 48 which extend respectively through a pair of apertures 50 provided in the wick 12 whereby to locate the wick both horizontally and vertically and hold the wick against accidental displacement in any direction.

In constructing the ink applicator, the capsule 22 is filled with the desired quantity of ink and is internally pressurized to tension the wall of the capsule, the purpose being to utilize the tension to effect a tearing of the capsule wall when punctured so as to enlarge the rupture and thus insure ink flow to the wick 12. An inexpensive method of tensioning the capsule wall is to fill the capsule 22 with ink with the capsule supported only at its filler neck such that the weight of the ink distends the caspule wall, and then tie oi the capsule neck 24 close to the body of the ink to hold the capsule wall tensioned. If

, 3 Y desired, a common knot may be [tied in the filler neck or the capsule 22'may be otherwise sealed against leakage. Another way to pressurize the capsule 22 would be to partially inflate it with air or other gas. VAfter tensioning the wall of the 'capsule Z2, the capsule is placed in the container 10 and assumes .approximately the shape shown Vin FIG. 9, due lto van optimum supply of ink, the shape of the container 10, and tension of the wall of the capsule causing the upper curved surface of the capsule to project somewhat above the edges of the container. However, on applying and clamping the container ktop wall 32 in place,

the ink in the capsule 22 is displaced into Ithe upperV corners of the container 10, as shown in FIG; 4, with the upper surface of the capsule 22 against the underside of the cover v4and overlying Ithe puncturable vane 31. Thus, a sharp pointed tool may be inserted through the vane Y 31 into and puncture the latex capsule 22 whereupon the tension force of the capsule wall will act to tear the same at the puncture point and release the Vink for ow to the wick 12. v

The modification ofFIGS. V2 and 8 is similar tothe previously described link cartridge and, therefore, like characters of reference, designate like parts. The modication differs from the previously described cartridge in that the stem portin34 of the T-shaped wick 12l is disposed between the upper rounded surface of thc capsule and the underside of the container top Wall 32 so that the wick will be adjacent to the point of the puncture Iand receive ink immediately following the puncturing lof the capsule. In addition, the wick portion 34 overlies the puncturable vane 31 `and prevents discharge of ink through the vane hole atthe time made. Y Y
